Density Practice

What is the formula for calculating density?

• D = V ÷ M

• D = M ÷ V

• D = M - V

• D = M + V

What does density tell about an object?

• How light an object is

• How the length affects the width

• How much space an object takes up

• How closely packed the particles are in an object
